Set a user's password to never expire

1.   If you haven't yet installed the Microsoft Online Services Sign-in Assistant and the Windows Azure Active Directory Module for Windows Power Shell, do that first. For a link to the downloads and instructions, see Step 1: Install the required software in the article Connect to Office 365 PowerShell.              
2.   Open Windows Power Shell as an administrator:        
   1. In your search bar, type Windows Power Shell.                      
   2. Right-click on Windows Power Shell and select Run as Administrator.            

      

                            
3.   The Windows PowerShell window will pop open. The prompt C:\Windows\system32 means you opened it as an administrator.        

   

                 
4.     Run the following cmdlet (we say "run the cmdlet" which means to type the following command at the PowerShell prompt):                  

   Connect-MsolService

                         
5. In the Sign in to your account page that opens, enter your admin credentials to connect to the service, and click Sign in.                
6. Run the following cmdlet to set the password of one user to never expire:                  

   Set-MsolUser -UserPrincipalName <name of the account> -PasswordNeverExpires $true

                   

   For example, if the name of the account is Ina@contoso.com, you'd type the command like this: 

                     

   Set-MsolUser -UserPrincipalName Ina@contoso.com -PasswordNeverExpires $true

                   

   If you get a red error message, there's probably a typo or an extra space.  Try again!  Or, copy and past the above to the PowerShell prompt, and use the arrow key to erase <name of the account> and enter the real name of the account. 

                 
7.         

   When you're successful, the PowerShell prompt appears for the next command. It doesn't display anything like "done" or "success."

                 

Find out whether a user's password is set to never expire 

1. Run the following cmdlet:                  

   Connect-MsolService

                         

2. In the Sign in to your account page that opens, enter your admin credentials to connect to the service, and click Sign in.  

                 

3. Run the following cmdlet:

                     

   Get-MSOLUser -UserPrincipalName <user ID> | Select PasswordNeverExpires

                   

   For example, to see the status for Ina@contoso.com, you'd type the following:

                     

   Get-MSOLUser -UserPrincipalName Ina@contoso.com | Select PasswordNeverExpires

                   

   The following picture shows how I set the password to never expire, and then ran the command to verify it is now set to never expire:
